During his time at Emerson, he practiced the craft of play by play by spending many nights in the old Boston Garden, calling games from high above courtside into his trusty tape recorder. He would astound the regular news staff at WECB, the Emerson carrier current station, with after game interviews, and up-close reflections on the actions of the night during the 10 PM extended news broadcast.

In addition to his Packers radio work, Larrivee hosts the team-produced Inside Lambeau television program which previews upcoming games and airs every week on several Wisconsin television stations. He also does a daily sports commentary segment called The Back Page, which originates from Packers flagship WTMJ-AM (620) in Milwaukee, and is syndicated to stations throughout Wisconsin and Northern Illinois and the Upper Peninsula of Michigan. Larrivee also does sportscasts for WTMJ when the station's regular sports anchors for their morning and afternoon shows are on vacation.

At crucial moments at the end of games, Larrivee refers to a clinching point as "The Dagger", which is perhaps one step under the proverbial "nail in the coffin." For example, after the big play, he will say, "and there is your dagger!" This 'catch phrase' has become synonymous with Larrivee and it is believed that he is the announcer that has led a surge in other announcers' using the phrase as well. An incorrect 'dagger' had never been called until the 2012 NFL season in which he presumed a Packers victory near the end of a September 24 game against the Seattle Seahawks, but the Seahawks scored a controversial touchdown to give them the victory. In 2011, Wayne teamed up with Sheboygan, WI based advertising agency, DuFour Advertising, to start selling merchandise with his signature phrase. "And There Is Your Dagger" merchandise is available on YourDagger.com.

Another well known catch-phrase of Larrivee's is "Ring It Up!", used typically as emphasis for a three-point basket made, and, of most recent note, for the buzzer-beating overtime 3-point basket on the Westwood One radio network broadcast of the first round contest between Western Kentucky University and Drake University in the 2008 NCAA Division I Men's Basketball Tournament.
